If mine goes out, Take cover. Sign your Will, things are coming to an end.
Seriously, if it goes out, its a very serious storm with Tornadoes and Hail (and comes from south west seems worst). Now thats not including the Spotbeams of local channels from Huntsville, AL. I was warned that they would be week in my area.
Anyways, I get 120+ on both 110 and 119 pretty much all the time. I took extra care to align my dish. My sat guy said he's never seen both 110 and 119 pegged out. Some stations stay peg out.
Last storm that came through, We lost Sat for 15 mins (>spot beams , about 3-5 mins on others), Cable went out for 12 hours with internet out 16 hours. Electricity stayed on funny, thing, goes out when the sun shines usually. After the main part of that storm came through, I was diggin a trench out from my hous to the backyard to eleviate drainage problems, water was actually pushing up into my sunroom from under concrete slab through the cracks in the floor.
Anyways,
back to your question, If your sat install guy cares and takes pride in his work, they can get you a signal ( at least in the central time zone areas of TENN, AL.) that won't show fade unless its really bad out. IF not get to tweaking.
